With temperatures rising more day by day, one of the biggest concerns many of us face is body odour. As the heat intensifies, so does the smell. It can be difficult to navigate social situations, as you are aware of your odour, and that can affect your confidence and cause you to feel very anxious and stressed. It also does not give a good impression when you are meeting new people. Many people opt for deodorants, body roll-on perfumes, mists, etc., to tackle this, but these solutions do not last long. The issue not only stems from the heat, but also from other lifestyle factors like what you eat, what kind of clothes you wear and your bodily hygiene habits. While these are all temporary solutions, there is something that can help you get rid of bad odour for the long term—hypochlorous acid. According to Dr. Neera Nathan, who is a dermatologist with training from Harvard University, she asserted that What Makes Our Sweat Smell?sweat itself doesn't have a bad smell. The problem starts when the sweat mixes with the bacteria that live on your skin. Hypochlorous acid is an antiseptic, which means it's really good at reducing the amount of bacteria on your skin. By reducing these bacteria, it stops your sweat from developing that unpleasant odor.The Cleveland Clinic explains that hypochlorous acid, often shortened to HOCl, is something that already exists inside your body. It's produced by your white blood cells, which are like the soldiers of your immune system. Their job is to protect you from all sorts of invaders, like infections, harmful bacteria, and just general unpleasantness that shouldn't be there.Scientists figured out a way to make HOCl outside the body a long time ago. They discovered that by using a process called electrolysis to break down a simple solution of saltwater, they could create this powerful antimicrobial compound. It works to fight the bacteria that can get trapped in your pores and cause acne, helping to keep your skin clear and healthy.Why Use Hypochlorous Acid for Body Odor?On her TikTok page, Dr Nathan explains that it is a component that our own bodies produce as part of our immune system to help us fight off harmful bacteria and infections. Because of its natural ability to kill bacteria and also reduce inflammation, it's often used in skincare products. So, if you're already using it on your face to help with breakouts or calm down acne and eczema, you might already have a bottle of this spray in your bathroom without even realising its potential for tackling body odor.Dr. Nathan explains that if you often find yourself smelling during the day, or if you really notice a smell after you've been exercising, hypochlorous acid can be a game-changer. You can take the same hypochlorous acid spray that you might use on your face to prevent pimples and simply spray it on your armpits, your body, or even your feet to get rid of the bacteria that makes your sweat smell bad. You can spray it on at any point you want to neutralise the odour. It's a quick and easy way to feel fresher, and according to Dr. Nathan, it's something you'll thank her for later once you experience how well it works to keep you smelling clean.
